Which organisms was were the first to colonize land about 475 million years ago?
Plants appeared on land about 475 million years ago, and the evolutionary history of the plant kingdom reflects increasing adaptation to the terrestrial environment. The colonization of land by plants transformed the biosphere.
What is endosperm quizlet?
Endosperm. Is a tissue produced inside the seeds of most of the flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein. Primary endosperm nucleus. Results from the fusion of the male.
Why is green algae the ancestor of plants?
All green algae (Chlorophyta) and plants share a common evolutionary ancestor. They both contain the photosynthetic pigments chlorophyll a and chlorophyll b. The two lineages diverged between 630 million and 510 million years ago.
What is the evidence that land plants evolved from green algae?
Evidence shows that plants evolved from freshwater green algae, a protist. The similarities between green algae and plants is one piece of evidence. They both have cellulose in their cell walls, and they share many of the same chemicals that give them color.
What is the edible part of orange?
Complete answer: The edible portion of orange is endocarp which is divided into segments; the fibrous core part at the centre and the outer membrane. These segments mainly contain juice sacs. The peel of orange has several oil glands.
Why does fruit exist?
One of the main functions of a fruit is to spread the seeds and allow the plant to reproduce. Therefore, all flowering plants produce fruit, regardless of whether the fruit is edible, sweet, or soft.
Which gas began to increase in the atmosphere as a result of photosynthesis by autotrophic prokaryotes?
Photosynthetic organisms also remove large quantities of carbon dioxide from the atmosphere and use the carbon atoms to build organic molecules. Without Earth's abundance of plants and algae to continually suck up carbon dioxide, the gas would build up in the atmosphere.
Which of the following traits was most important in enabling the first plants to move onto land?
Which of the following traits was most important in enabling the first plants to move onto land? the development of sporopollenin to prevent the desiccation of zygotes.
When did moss evolve?
about 320 million years ago The earliest known moss fossil is from the early Carboniferous period, about 320 million years ago.
Are all algae aquatic?
The majority of algae live in aquatic habitats (Current Biology, 2014). Yet, the word "aquatic" is almost limited in its ability to encompass the diversity of these habitats. These organisms can thrive in freshwater lakes or in saltwater oceans.
Which of the following is not a type of primary meristematic cell found in apical meristems view available hint?
Which of the following is not a type of primary meristematic cell found in apical meristems? The vascular cambium is a type of cell found in lateral (not apical) meristems and is involved in secondary (not primary) growth.
Which statement S correctly describe s the interactions between plants and fungi?
Which statement(s) correctly describe(s) the interactions between plants and fungi? Plants are harmed by fungal pathogens. Plants depend on fungi as mutualistic symbionts.
What specific evidence is there that the chloroplast in green algae is the descendant of a free living cyanobacterium?
Cyanobacteria and chloroplasts of plants and algae share thylakoid membranes with galactolipids and sulfolipids, various components of photosystems, and photosynthetic pigments. These traits of substance, structure, and function as a whole were taken as good evidence for the cyanobacterial origin of chloroplasts.
Can green algae do photosynthesis?
Algae are a diverse group of predominantly aquatic photosynthetic organisms, including cyanobacteria, green algae and other eukaryotic algae. They account for more than 50% of the photosynthesis that takes place on Earth. Photosynthetic efficiency is higher in algae than in higher plants, because of a wide …
What evidence led scientists to think that green algae were the ancestors of plants?
3: What evidence led scientists to think that green algae were the ancestors of plants. Scientists have found that plants and green algae contain the same form of chlorophyll.
Which piece of evidence supports the argument that land plants evolved due to the presence of microbes?
Which piece of evidence supports the argument that land plants evolved due to presence of microbes? The chloroplasts of land plants, which allow them to carry out photosynthesis, is a structure similar to cyanobacteria.
What is edible part of coconut?
Coconut is a type of drupe in which the fibrous part is the mesoderm and the stony layer is the endoderm. The edible part is the seed or its endosperm which is cellular is opaque and white in a mature coconut and nuclear in the green coconut's water.
What is edible part of banana?
The edible part of banana is endocarp and the less developed mesocarp. Bananas are berries developing from the multicarpellary or monocarpellary syncarpous ovaries. The endocarp is membranous and thin, the mesocarp is fleshy while the epicarp forms the rind of the fruit.

Is coconut a fruit?
Botanically speaking, a coconut is a fibrous one-seeded drupe, which is a fruit with a hard stony covering enclosing the seed. A seed is the reproductive unit of a flowering plant. From a reproductive point of view, a seed has two basic parts: the embryo root (hypocotyl) and the embryo leaves (epicotyl).
When cells perform photosynthesis they transform energy from one form to another which of the following takes place during photosynthesis?
More than one answer may be correct. When cells perform photosynthesis, they transform energy from one form to another. Which of the following takes place during photosynthesis? Chemical potential energy is stored in the bonds of carbohydrate molecules.
When oxygen is released as a result of photosynthesis it is a by product of which of the following?
